Ports for External Devices

The router provides three ports on the craft interface for connecting external management devices to the Routing Engine and the JUNOS software:

• Console port—Connects a system console using an RS-232 serial cable.
• Auxiliary port—Connects a laptop or modem using an RS-232 serial cable.
• Ethernet management port—Connects the Routing Engine to a management LAN (or any other device that plugs into an Ethernet connection) for out-of-band management of the router. The Ethernet port is 10/100 megabits-per-second (Mbps) autosensing and requires an RJ-45 connector.
